The body fossils are generally positioned at the focal points of the fan-shaped scratch marks.
A former teacher of mine was the late Adolf Seilacher, who was a leading authority on trace fossils and who for obvious reasons preferred to be called “Dolf.”
One of the few features that are uncontroversial is the body size: The fossils measure usually 1-5 cm in length.
The fossilization of Kimberella specimens was most likely based on rapid burial with sand during storm events.
